Tree Beekeeping Climbing with a Leziwo

My tree beekeeping friend Tomek demonstrates an ancient form of tree climbing used by Polish tree beekeepers, or Bartnik. In Poland the skill was almost lost after World War II, but Tomek painstakingly (I think he fell off a few times!) recreated it from old archive footage, and he now teaches this skill to others. The technique is also used in Belarus, Ukraine and Lithuania. Tomek makes it look easy, but I've tried this method and it is very difficult to master. I will get my leziwo next month, so hopefully I will improve and not fall off myself.
